The problem appears to be at irqlist.c:49 or so:
sprintf(buf, "/proc/irq/%i", number);
dir = opendir(buf);
do {
entry = readdir(dir);
I'm assuming that the readdir on a failed opendir is the problem here,
although I haven't attached a debugger. The obvious fix is just to make
the do loop conditional on the opendir succeeding - I'll give it a shot
tonight and let you know.
Cheers,
